Professional Journey

I'm Qifei Li, a security engineer with over 10 years of experience working across Europe and Asia. Currently, I lead information security at NIO Inc. in Munich, where I've transformed security operations through innovative SIEM solutions and automation.

Research & Innovation

My work spans from theoretical cryptography to practical security engineering. At NEC Laboratories Europe, I architected secure AI systems using Trusted Execution Environments. At Alibaba Group, I pioneered privacy-preserving machine learning platforms using homomorphic encryption.

Academic Background

  • M.S. Computer Science - Harbin Institute of Technology
  • B.S. Computer Science - Harbin Institute of Technology
  • Ph.D. Drop out - University of Luxembourg (Cryptography)

Beyond Security

Based in Heidelberg, Germany, I balance my technical work with community building. I organize Munich's Friday poker nights for our 30-member expats club, where game theory meets social networking. This blend of analytical thinking and human interaction enriches both my professional and personal life.
